Building The Atkinson Cycle Engine

This book describes how to build a model of James Atkinsonís second four stroke engine design which, like his Differential engine, completed all four strokes in a single revolution. This engine also had no gears, and a separate crankshaft. It is a good subject for an interesting model, and here Vince Gingery tells you how to build it. As with most Gingery projects, foundrywork is described for certain parts, but fabricating them should be straightforward
